At the moment we have just a simple mixer tap to fill our bath but want to renovate the bathroom and put in a themostatic mixer shower tap. We have chosen to get one of these as we don't fancy running pipes up the stud wall which isn't very thick yet we would like a shower. We have a combi boiler which reads 0.8 bar when not in use and goes up to 1.5 in use. All the taps I've seen apart from one which I don't like the look of say min 1 bar pressure, will that be ok? any advise on these type of taps will be gratefully recieved.
